What is disc password for MacBook Air

Hey there MacBookAirdiskpasword,

Thanks for posting in Apple Support Communities. A Disk Password is what is required to log in to a Mac that has FileVault enabled. FileVault is a security feature on your Mac that encrypts the data on your disk and requires a password when setting up to prevent unauthorized access to your information. If you do not know what this password is, you can follow the steps in the "Reset your password or change your FileVault recovery key" section of the article below which also provides additional information on FileVault.

Use FileVault to encrypt the startup disk on your Mac

We hope this helps.
